How stars live, sentence 1

For most of its life a star is a tug of war held in balance: gravity pulls everything inwards, and the pressure of hot gas pushes outwards, like a balloon whose rubber squeezes in while the air pushes out.

Who acts: star, gravity, pressure, rubber, air · What happens: be, hold, pull, push, squeeze in, push out · To what, where: tug, war, balance, everything, hot gas

This is a sentence of the lesson «How stars live» of the space course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (star, gravity, pressure, rubber), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R2-punct-next ×1, R5-strong ×2, R7-rel-agree ×2. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
